Surveillance Software Scanning File-Sharing Networks Led To 12,000 Arrests (nbcnews.com) 106

Mr. Cooper was a retired high school history teacher using what NBC News calls those peer-to-peer networks where "the lack of corporate oversight creates the illusion of safety for people sharing illegal images."
Police were led to Cooper's door by a forensic tool called Child Protection System, which scans file-sharing networks and chatrooms to find computers that are downloading photos and videos depicting the sexual abuse of prepubescent children. The software, developed by the Child Rescue Coalition, a Florida-based nonprofit, can help establish the probable cause needed to get a search warrant... Cooper is one of more than 12,000 people arrested in cases flagged by the Child Protection System software over the past 10 years, according to the Child Rescue Coalition... The Child Protection System, which lets officers search by country, state, city or county, displays a ranked list of the internet addresses downloading the most problematic files...

The Child Protection System "has had a bigger effect for us than any tool anyone has ever created. It's been huge," said Dennis Nicewander, assistant state attorney in Broward County, Florida, who has used the software to prosecute about 200 cases over the last decade. "They have made it so automated and simple that the guys are just sitting there waiting to be arrested." The Child Rescue Coalition gives its technology for free to law enforcement agencies, and it is used by about 8,500 investigators in all 50 states. It's used in 95 other countries, including Canada, the U.K. and Brazil. Since 2010, the nonprofit has trained about 12,000 law enforcement investigators globally. Now, the Child Rescue Coalition is seeking partnerships with consumer-focused online platforms, including Facebook, school districts and a babysitter booking site, to determine whether people who are downloading illegal images are also trying to make contact with or work with minors...

The tool has a growing database of more than a million hashed images and videos, which it uses to find computers that have downloaded them. The software is able to track IP addresses — which are shared by people connected to the same Wi-Fi network — as well as individual devices. The system can follow devices even if the owners move or use virtual private networks, or VPNs, to mask the IP addresses, according to the Child Rescue Coalition.... Before getting a warrant, police typically subpoena the internet service provider to find out who holds the account and whether anyone at the address has a criminal history, has children or has access to children through work.

A lawyer who specializes in digital rights tells NBC that these tools need more oversight and testing. "There's a danger that the visceral awfulness of the child abuse blinds us to the civil liberties concerns. Tools like this hand a great deal of power and discretion to the government. There need to be really strong checks and safeguards."

      Soundslike law enforcement is wise enough to investigate before they pull the trigger on a warrant. But yeah, lets protect child porn downloaders and child abusers while mass surveillance on the public goes unchecked. Also Sowden and Assange are still in exile/jail too. But I guess these writters have priorities....

        This article shows a good use of the tools, and as you mentioned, this looks like a case where they are doing it correctly. At least according to the story the tool is used as a starting point looking for specific violations (rather than fishing for everything then back-filling whatever fits), followed by using those results to help establish probable cau

          This is the real issue. We're not mature enough as a society, and we don't have strong enough protections for the common person to avoid accidental use, misuse, and outright abuse from organized surveillance. Doing an end run around warrants by letting private companies create databases of personal information is only more evidence of our disregard for what little protections we do have.

        Yes, but that might not always be the case. Anything that "think of the children" always has ramifications for adults in curbing their freedom of speech.

        Like, really, a lot of pictures of naked children, exist, because of facebook. Facebook has moms and dads all uploading photos of their kids, in any state of dress, doing things that can range from cute and funny to "ha ha, that's so inappropriate" , of course people who have a fetish for that content, will collect that stuff along with exploitative images.

        The people who are actually producing child porn, aren't always adults either. Minors in bad situations may make it themselves to try and get out of their bad situations. You will never really be sure what the context of any specific image or video is, which is why humans have to review these kinds of videos, and you can't have people reviewing videos of explicit content while the laws are worded in a way that doesn't exclude the reviewer, but you also don't want a reviewer to be collecting it themselves either.

        Like the problem with eBay's PI (Prohibited Items) department is that someone has to look at the listing, and sometimes the listing might be for something that is illegal, and even looking at it, or having the video/image puts that reviewer in legal peril.

        Unfortunately people will almost never push back against "think of the children" laws, because to do so paints them as the villain. (Where opposing abortion or medicare for all is villainous, it's not explicitly targeting children, just everyone.)

        Like if anything, laws regarding underage children need to be separated between "content that is of actual children or can be confused for actual children (eg video games with children models) versus "this can't possibly be confused for real children (Manga, Anime, Video games like "The Sims" or "Second Life")

        With content of actual children, it further has to be separated between things a child does to another child (eg no adult was involved in producing it) and those that are done by an adult (eg a family member, teacher, or someone with power over them) with predatory intent. Children do things to each other all the time, sometimes by being goaded into it, and sometimes because they want to show off, and that includes flashing each other's junk to each other with no sexual purpose behind it. With current generations of smartphones and how kids will have each others numbers/email/snapchat/etc (Snapchat is used by porn artists a lot) , there's a lot of unintended consequences all around if you make the defining aspect the split between age 17 and 18. People who have older boyfriend/girlfriends of only a few months, can easily get the other in hot water, or put them in hot water if they decide to break up. That's where a lot of revenge porn comes from.

        Revenge porn comes from having a falling out with someone and then finding their photos they don't want to share and then sharing it with people removed from context. Sometimes that's stuff that was mutually shared and sometimes that is stuff that people don't quite understand the ramifications of creating. One shouldn't be punished perpetually for crap they did under the age of 18, and shouldn't be punished for having friends under the age of 18. However the way laws are written, the second you're 18, you're not allowed to know anyone under the age of 18, because you put yourself in peril from any communication with them and put them in danger if that person under the age of 18 reads more into a conversation than what was intended.

          I am very naive. Is child porn, children experimenting with children, or Adults with Children or both? Which one? I am also wondering if a obsessed person gets gratification from the photos, or are the photos a trigger for other activities? Can the photos serve as a limiter for other obsessive activities?

        lets protect child porn downloaders and child abusers

        You are conflating two different things.

        There is no evidence for a causative effect between viewing CP and abusing children.

        The evidence actually leans in the other direction. Countries with more permissive CP laws tend to have less child abuse. CP can give a pedo an alternative release.

        There is also evidence from the world of adult porn. Men who are "porn addicts" are often socially withdrawn and don't engage with women. That is viewed as dysfunctional, but in the case of men attracted to children rather than adult women, it is what we want.

        We can create CP with CGI, deep fake technology, or adult actors posing as children. Make it available and it is likely that abuse of children will decline. Japan has gone the furthest, even making child-like sex dolls (illegal in America), and Japanese recidivism rates have fallen.

        • Fine. See a psychologist and get a prescription, then you are allowed to possess and not distribute CGI CP for ... therapeutic reasons or whatever. That might be a net benefit to society, maybe, I'm not a psychologist. Otherwise if a bunch of kid sized sex dolls are detected in the mail to your address, or certain downloads, red flag, your ass gets investigated.

          There's no way to expect anyone to condone that crap openly and freely because it muddies the waters between therapy and profiting from child abu

          • See a psychologist and get a prescription, then you are allowed to possess and not distribute CGI CP for ...

            There is no evidence that CGI CP is harmful, and it is likely helpful. So there is no justification for stigmatizing it and making it harder to obtain. You are just propping up the market for illegal kiddie porn ... which is much more likely to be real rather than CGI.

            Otherwise if a bunch of kid sized sex dolls are detected in the mail to your address, or certain downloads, red flag, your ass gets investigated.

            That is idiotic. You are persecuting the people who are making an effort to deal with their affliction in a harmless way.

          Given virtual child pornography is legal, it doesn't make any sense that a doll/mannequin/whatever would be illegal, especially when you follow the legal theory of the ruling, which is that the government doesn't have any jurisdiction over what you can imagine in your head. You probably just won't find anybody manufacturing them here due to nobody wanting to be known as "that guy that makes child sex dolls"

            You are correct. They are not illegal. I misremembered the CREEPER Act, which would have banned them. The bill passed the House but never passed the Senate and never became law.

          • Depends where you are. The UK widened their definition a few times in succession, each time justified by the government as closing 'loopholes.' Currently it doesn't just ban the obvious child abuse images, it also bans any material which gives the 'impression' of a child, and artistic depictions. They even go so far as to ban sexual depictions of non-human characters, if the characters have child-like characteristics.

            A very common practice in the UK is for parliament to over-prohibit things, and then depend

            • Have they defined what child-like features are?

              This is the same reason why hate speech laws will never work in the long run -- they ultimately can't be clearly defined by laws and whether they're enforced ends up just being how somebody perceives it, even when their perception doesn't follow a reasonable person standard.

      Lots of them are probably innocent. I stopped using eMule years ago because there is so much illegal stuff on there, and often it's disguised as other things so you have no idea until after you download it. An episode of an old TV show you can't find anywhere else or a PDF of an old magazine turns out to be something nasty.

      Of course I used a VPN and encrypted storage but still the risk is too great. Even if they do eventually find you are innocent after checking your computer you still had your door smashed in and all your stuff taken and combed through for months and years.

            A _lot_ of time has been invested into it (rightfully). It's 12,000 over 10 years. 1,200 a year, so 100 a month. This is world wide.
            Given that there are going to be a lot of investigations going on, and this tool seems like it's one of the strong ones in the arsenal, I'm thinking the figures seem fairly sane for a rigorous investigation, given the candidate cohort.

          • We would hope that the officers working this are intelligent, well-trained professionals.*

            We know that the screen shows search terms, number of known child porn files downloaded, and sorts by priority. Meaning we know it's fairly easy for officers to concentrate on the particularly bad guys.

            We don't know that they do, but normally people do what's easy, and apparently this system makes it easy to right in this regard.

              Interesting that it groups the results by IP address. Given that IP addresses are shared and over time will be used by many different people that's a bit worrying. So the people who made this software understand this fundamental issue with their software? Do the cops?

              • As noted in the summary, one of the first steps cops have to do after pulling a report from this software is ask the ISP who had the IP at the specific timestamps that the files were downloaded. So yes, the cops understand the time is important, and even if they didn't understand that the ISPs do. The ISP can't give them an address without being given a timestamp.

What saved him was the boxes were bought in a lot and he'd never unsealed them. That and he's fairly well off so he had the money to hire lawyers.

It's a lot like the problem of cops going after drug users rather than drug dealers. It's easier and leads to more arrests, but it does less to solve the problem.

      • They go beyond just allowing it to exist. They take over major sites and move them to government servers with faster and better connections, then explicitly authorize cooperators to personally distribute material. There was some small news attention the first time they did this, for 11 days. They've since done it for months on end on many other sites, one time they ran the largest site in the world, with 500k members, for 11 months, and only stopped because a journalist investigating the site figured out it
        • What is the crime you see the government committing that is worse than the mass production and distribution of child porn? That they run the servers for a few months to gather evidence?

          This is the lesser evil of just letting these people continue what they've been doing. If you have a better idea that will still put these subhumans behind bars you should share it.

          The world is an ugly place sometimes and yes in this case the ugly means does justify the ends.

          • Mass distribution is worse than possession. They're operating as the largest distributors in the world to bust people for simple possession.
            My better idea is that in a world of finite police resources, 100% of effort should be dedicated towards the much harder job of tracking down and prosecuting people actually abusing children themselves. These massive operations are geared exclusively towards nailing people just for having what they're distributing. That should not be the highest enforcement priority,
      • when they allow it to exist as a honeypot so they can arrest a bunch of people downloading it rather than going after those who distribute it.

        No one is forcing anyone to download child porn just like no one is forcing people to do drugs. The people doing this are going out of their way to find this stuff.

        It's a lot like the problem of cops going after drug users rather than drug dealers.

        By going after the users, police are doing two different things. 1) removing those who purchase which reduces demand and

    Ok, this looks to work over VPNs and torrent sites.
    They have a large database of hashes of bad pics, for example lets call one of them pornpic1.gif
    They see a file out there with the same size but named legalporn1.gif and decide to track it. So they have to download the file, to at least memory in order to get the hash. I don't know of a technology that allows you to get a hash of a network transmitted file without downloading it.
    Then how do they.track through the VPN and with a person switching wifi connections through various ISPS.

    Lets go with the very simple setup. A person at home using no VPN , who uses their desktop computer to connect to a HTTP website. Even then they would need access to either the server or the client or they are doing a MITM attack. it would explain how they are just requesting all ipad 3 since they just have the user-agent string.

      For torrent, it's trivial - both magnet links and .torrent files contain the hash of the content. So you must get the hash before you could even try to get the content. No problem there - no content needed.

      For protocols that do not provide a hash without getting the content:

      First, the software can provide the search terms. Only for results that come up for clear child-porn searches, it would be needed to download at least some of the content once for thr relevant URLs.

      With a 1 MB image, you could download the first 1kb, 8000 bits, and check the hash of that first. That first 0.1% of the file is pretty good at distinguishing; 8000 bits is unlikely to match perfectly by chance.

      The relevant statutes typically including wording such as:
      --
      It is an affirmative defense to prosecution that: ...
      âthe conduct was for a bona fide educational, medical, psychological, psychiatric, judicial, law enforcement, or legislative purpose;

    Every Fourth Amendment challenge of the use of the technology has failed in federal court.

    The USA is now a police state [wikipedia.org]. Thanks to the wars on drugs, terrorism, child porn, drunk driving, I am stopped at 11AM by a police barricade asking, "Papers Please!"

    Fortunately, I am a white guy so I can give a teeny tiny bit of push-back - "Uh, why are we being stopped?"

    "Governor (R) wants to check seat-belt usage."

    "Only on this road?!"

    The Fourth Amendment and the rest of the Constitution is nothing but a fucking piece of paper now. And for the gun nuts - without our other Civil Liberties, the Second Amendment is just a temporary favor granted to us for the time being.

    • I don't think the 4th amendment applies if you traffic humans in the back of an open truck, with them chained to the sides of the rails. I don't think it applies if you mail a postcard with a threat to the president on it. I don't think it applies if you set up a cocaine stand next to your daughter's lemonade stand.

      All of these things are public acts, with no expectation of privacy. Packets on the Internet are like little postcards. The 4th might reasonably be applied to encrypted traffic in transit, as

      • "Rights have limits."

        No they do not. Privileges and license have limits. Rights do not have limits. If there are limits they are not Rights, they are licenses.

        • On those grounds you may edit the Wikipedia entry on Fundamental rights [wikipedia.org] to reflect your point-of-view, but I doubt your edits would stand for very long.

          That rights have limits seems common sense, even if the rights are only restricted due to contention with somebody else's rights. That rights may be restricted, as the article states, due to "compelling state interest" is something with which you may disagree, but it doesn't alter that fact that rights may have limits and still be rights.

    • 4th Amendment doesn't apply to things you put out in public which is why police can trawl through your garbage providing you can is out on the street without a warrant.
      The service collated openly accessible information, i.e. stuff you publish to the wider community without knowing it to establish probable cause, then the police go get a warrant.

      • The cops are using the information as an excuse to search non-public parts of the accused computers. THAT is Fourth Amendment violation.

        But it doesn't matter anymore because the Fourth Amendment was neutered on 9/11/2001.

        • search non-public parts of the accused computers.

          False. At no point are police searching anything you haven't made public. They do not have access to your computer. The only thing they see are the files you made public. The only evidence they have that links to you is the IP address you shout out across the internet along with resulting fingerprinting details.

          It's as much of a 4th amendment issue as a police officer knocking on your door and asking you if you have kiddy porn and you replying yes.

          • search non-public parts of the accused computers.

            False. At no point are police searching anything you haven't made public. They do not have access to your computer.

            Wrong. They get a warrant to search non-public areas of the accused's computer. It's in the article.

            Critics of the software say that indicates that it could be searching parts of the computer that aren't public, which would be a potential Fourth Amendment violation.

            • Exactly. They get a warrant ergo not a 4th amendment violation. Everything prior to the warrant is public information.

    • The USA is now a police state [wikipedia.org].

      Every government is a police state. You didn't even read your own Wikipedia link. Quoting the first sentence from Wikipedia:

      "A police state is a government that exercises power through the power of the police force."

      So yeah, the US has a police force. That isn't bad.

    From the headline

    Inside the surveillance software tracking child porn offenders across the globe

    Assuming this is an effective tool, and lets be honest it probably is since most people aren't that secure or tech savvy. That means 12,000 out of 7.8 billion Ok lets only include people with access to the internet 4,648,228,067 (https://internetworldstats.com/stats.htm) so that is 0.0003% of the population are even into child porn, or 3 in a million people over 3 years. or 1 person per million per year. Assuming they are all men 2 out every million men, clearly cause for alarm.

    from (https://www.theworldcounts.com/challenges/people-and-poverty/hunger-and-obesity/how-many-people-die-from-hunger-each-year) 3.1 million children die from hunger each year.

  • People in the modern era need to go back to medieval strategies because they had it figured out. Don't build a wall. Don't post a guard. Build a trap and make it look like safe. THAT is how you stop bad people. I'm glad these people get it.
  • They're also scanning completely innocent people's files too. It's like cops going down the street and searching every house looking for one person they don't even know is there.
  • To help fight exploited children a FRC can be be used. Create a database of school photos. Then when an exploited photo is found run recognition software like amazons to match the face of the child to identify the school child goes to so you can follow up and save a child for other ideas like router that detect chid abuse see http://ideasthatchangetheworld...

    Sounds like they are doing a great job protecting and rescuing those copies of bits. The children must be so relieved.
  • How does it get around VPNs?

    • their might be a unique id associated with the p2p node and it tracks that across ips you subpena the vpn to monitor traffic going to x ips and see which ip requested it
    • That part is probably bullshit. If they could really do that I don't think they would be dumb enough to boast about it like this. The truth is they own the Tor network and are probably mostly nabbing people who think they can't be tracked if they use Tor.

      For a VPN they'll have to do the work of asking for their cooperation in finding the user, something that is far from impossible. Whatever system they claim to have it's not automatically tracking across VPNs though.

The data in motion is encrypted, thus rendering the hashes useless on the wire.

    A perfect system that does that seems OK - the images are on a public server. But how difficult is it for someone to spoof IP addresses and make it appear that an image was uploaded from a different computer? What other corroborating evidence is required?

    In addition to various attacks like "spear fishing", does this create a possibility of framing a factually innocent person for child porn distribution? Keeping in mind that some innocent people may not be very skilled at cyber security.

    Hack someones computer and put a few CP images on it. Then fake an upload, or do the upload from the hacked computer. Where does that leave them legally? This scanning program makes the problem worse because the hacking victim's upload will be automatically detected, it doesn't require anyone to tip off authorities (which might look suspicious).

    How can you distinguish between an innocent person who had been hacked, and a guilty person who claims that they must have been hacked.

Technology is dominated by those who manage what they do not understand.
